Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.  We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.   ABOUT THE ROLE We are looking for a Senior OR Staff Developer Experience Engineer to help shape how Horizon3 engineers build, test, release, and operate software. The Developer Experience team owns the foundations connecting local development to production delivery: developer tooling, CI/CD, build systems, container base images, artifact promotion, release gates, and approved agentic-development workflows. You will define technical direction, lead complex initiatives across engineering, and build reusable paths that improve delivery speed, quality, security, and confidence. This is a hands-on technical leadership role for an engineer who enjoys solving ambiguous problems, influencing across teams, and making the software lifecycle easier to use and operate. WHAT YOU’LL DO DEVELOPER PLATFORM STRATEGY, DELIVERY & OPERATIONS - Define the architecture and roadmap for local development, repository tooling, CI/CD, build systems, and release workflows. - Lead high-impact initiatives across engineering that reduce manual coordination and standardize the path from code change to production. - Build reusable GitLab CI/CD templates, runner capabilities, developer workflows, test gates, artifact promotion, release manifests, and rollback paths. - Establish sustainable practices for shared container images, build performance, reproducibility, scanning, signing, provenance, and supply-chain security. - Improve developer workflow and delivery observability through useful measures of setup time, pipeline health, release performance, and adoption. - Partner with Platform, Security, QA, and feature teams to make delivery foundations reliable, secure, and easy to consume. TECHNICAL LEADERSHIP & ENABLEMENT - Establish standards and paved paths for developer workflows, build and release engineering, and approved AI-assisted development. - Design safe agentic-development workflows that integrate with code review, testing, scanning, permissions, auditability, and Security requirements. - Turn repeated developer friction into reusable tooling, templates, documentation, migration guidance, and runbooks. - Mentor engineers, develop technical owners, and raise the engineering bar across Developer Experience and Horizon3. - Communicate complex technical decisions clearly and build alignment across Platform, Application Engineering, Data Engineering, Security, QA, Product, and Program Management. - Participate in design reviews, operational reviews, incident response, and continuous improvement.
